As the seasons change, the more you feel the cool air blustering outside. And … right inside your house? If your gas furnace is blowing cold air and putting a chill to your Arlington home, it’s time to reach out to Service Max Heating & Air Conditioning. Once in a while the loss of warm air from your gas furnace calls for a big repair, but often it can be an easy fix. Here are some of the main reasons your gas furnace may be blowing cold air instead of warming up your house.
Your furnace could be overheating
If you haven’t had routine maintenance done on your gas furnace for some time and you’ve neglected to replace your air filter, each could indicate why your furnace is blowing cold air. A dirty air filter can stop air from flowing freely through your furnace. When this happens, the furnace might overheat and cause the burner to shut down.
Your pilot light may have gone out
Sometimes a lack of warm air from your gas furnace can be related to something as simple as a pilot light that’s gone out. It’s possible, specifically with older furnaces, for a draft to smother a pilot light. Other causes of an extinguished pilot light are defective gas valves or a faulty thermocouple.
Your furnace is dirty
Just as a dirty air filter can result in issues for your gas furnace, so can other furnace components if they aren’t correctly cleaned. A dirty gas burner or flame sensor could cause your furnace to battle to stay lit and leave you in the cold.
Your ducts may not be properly sealed
When ducts are correctly sealed or if they have any cracks or holes in them, you may be losing a lot of heated air before it even reaches the vents throughout the home.
